How do you calculate the amount of Contacts without an email address assigned for each Account record?
Quickly deploy one of Rollup Helper's pre-built rollups named, "Number of Contacts without Email." The Number of Contacts without Email use case calculates the amount of Contacts without an email address assigned for each Account record. This use case deploys one Rollup Helper setting and one field, "rhuc_Number_Of_Contacts_Without_Email."
Once logged into your Salesforce organization click on the App Launcher or All Tabs and search for "Rollup Helper." Click on the "Deploy Pre-Built Rollups" tile and click Deploy next to the Number of Contacts without Email label:
You will also be able to view and edit the deployed rollup via the All Rollups page.
Now your outbound Sales team members can know which Contacts need their data updated.
